Case Study #8 Lanpac Plastic

LANPAC® resistance to plugging demonstrated in a
field test to remove iron from potable water

The Problem

Under the direction of Burns & McDonnell, a nationally known engineering/consulting firm, the city of Willmar, MN conducted a pilot study to determine whether an engineered packed tower could successfully remove 1.96 ppm concentrations of iron from potable water.

Why LANPAC® Was Chosen

According to Willmar’s Superintendent of Water Supply, Bart Murphy, results from their three-month feasibility study proved that iron could be removed effectively and economically utilizing a vertical tower packed with 2.3″ LANPAC®.

Meeting the Requirements

In the burns & McDonnell system, a filtration unit downstream collected the iron oxide that precipitated out of the well water.
